A good strategy is have all your towers max upgrade before getting another
if the next upgrade is expensive buy more towers and upgrade them until the rounds you are playing can get you the cash you need i hope this helps! copy this info to keep it around
Wow. That Turtle sure is Tough. He's gone into space, Been shot by a rocket launcher, Nuked at least 400,000,000 Times by Different players, Shot out of a tank, Burned by the sun, Been abducted, Jabbed by Millions of Spikes, and Been Shredded by a chainsaw, Yet, He Get's Right back up, Sighs a sigh of relief. And smiles, And then he's ready To go again.
